When an XmlDocument object is created as the result of a schema validating XmlReader object, the value specified to the SetTypedValue method is verified against the XML Schema Definition Language (XSD) schema for the XML document. If the value specified is invalid according to the schema for the XML document, an XmlSchemaException is thrown.
The SetTypedValue method is valid only when the XPathNavigator is positioned on an element or attribute node.
In the following example, the SetTypedValue method is used to update all price elements in the contosoBooks.xml file using the XmlNamespaceManager object to resolve namespace prefixes in the XPath expression.
Dim settings As XmlReaderSettings = New XmlReaderSettings()
settings.Schemas.Add("http://www.contoso.com/books", "contosoBooks.xsd")
settings.ValidationType = ValidationType.Schema
Dim reader As XmlReader = XmlReader.Create("contosoBooks.xml", settings)
Dim document As XmlDocument = New XmlDocument()
document.Load(reader)
Dim navigator As XPathNavigator = document.CreateNavigator()
navigator.MoveToChild("bookstore", "http://www.contoso.com/books")
navigator.MoveToChild("book", "http://www.contoso.com/books")
navigator.MoveToChild("price", "http://www.contoso.com/books")
Dim price As New Decimal(19.99)
navigator.SetTypedValue(price)
navigator.MoveToParent()
Console.WriteLine(navigator.OuterXml)
XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas.Add("http://www.contoso.com/books", "contosoBooks.xsd");
settings.ValidationType = ValidationType.Schema;
XmlReader reader = XmlReader.Create("contosoBooks.xml", settings);
XmlDocument document = new XmlDocument();
document.Load(reader);
XPathNavigator navigator = document.CreateNavigator();
navigator.MoveToChild("bookstore", "http://www.contoso.com/books");
navigator.MoveToChild("book", "http://www.contoso.com/books");
navigator.MoveToChild("price", "http://www.contoso.com/books");
Decimal price = 19.99M;
navigator.SetTypedValue(price);
navigator.MoveToParent();
Console.WriteLine(navigator.OuterXml);
XmlReaderSettings^ settings = gcnew XmlReaderSettings();
settings->Schemas->Add("http://www.contoso.com/books", "contosoBooks.xsd");
settings->ValidationType = ValidationType::Schema;
XmlReader^ reader = XmlReader::Create("contosoBooks.xml", settings);
XmlDocument^ document = gcnew XmlDocument();
document->Load(reader);
XPathNavigator^ navigator = document->CreateNavigator();
navigator->MoveToChild("bookstore", "http://www.contoso.com/books");
navigator->MoveToChild("book", "http://www.contoso.com/books");
navigator->MoveToChild("price", "http://www.contoso.com/books");
Decimal^ price = gcnew Decimal(19.99);
navigator->SetTypedValue(price);
navigator->MoveToParent();
Console::WriteLine(navigator->OuterXml);
The example takes the contosoBooks.xml file as an input.
